Abstract
L'invention concerne un procédé général permettant d'extraire des informations de distance de source à partir de n'importe quel rayonnement reçu, y compris des rayonnements électromagnétiques et acoustiques, sans que cela implique un temps ou une phase aller-retour quelconque, et par conséquent des radars véritablement plus passifs que les radars passifs actuels. Le procédé exploite le fait que le rayonnement provenant d'une source réelle doit comprendre des paquets d'ondes de bande passante non nulle, que les composants fréquentiels individuels d'un paquet d'onde doivent avoir une phase constante à la source, et que leurs phases instantanées doivent augmenter linéairement le long du trajet proportionnellement aux fréquences respectives, de façon que le gradient de phase traversant les composants soit proportionnel à la distance parcourue. Cela simplifie la mesure de gradient de phase naïve par scannage du gradient de phase à une vitesse contrôlée, et convertit le gradient en décalages de fréquences normalisés proportionnels à la vitesse de scannage et à la distance de source. L'invention concerne la simulation du décalage vers le rouge et l'accélération cosmologiques, mais à des niveaux mesurables par rapport à n'importe quel intervalle recherché, même avec du son. Les applications potentielles concernent notamment des radars furtifs et indécelables à des fins militaires, la capacité de localisation pour des services d'urgence, des radars véhicule de marchandises faible puissance et personnels, une simplification et des améliorations d'imageur radar et diagnostique, une télémétrie améliorée d'une manière générale depuis le sol jusque dans l'espace intergalactique, des systèmes de communication sans interférence comportant des récepteurs radio et télévision, une commande de puissance de téléphone cellulaire améliorée à multiplexage de distance de source (ou de division d'intervalle) et une durée d'accumulateur, et des diagnostics continus et transparents pour fibres optiques, circuits intégrés et lignes de transmission.
